An experiment was carried out at the experimental farm of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh during the period from January, 2011 to April, 2011. The study was conducted to evaluate the effect of gamma radiation on morpho-physiological characters of BARI soybean. Four levels of gamma irradiation viz. 200, 300, 400 and 500 Gy ?-ray from 60C source and control were irradiated on assigned two genotypes viz. BARI soybean 5 and BARI soybean 6. Data for growth analyses were collected at different days after sowing. Results revealed that the soybean varieties and gamma irradiation significantly affected morpho-physiological characters where BARI soybean 5 and 200 Gy ?-ray levels produced the greater results alone or combinations. This combination produced the tallest plant (37.42 cm), maximum leaf and branch plant-1 (23.15 and 2.10) at 75 DAS. 200 Gy ?-ray irradiated plants of BARI soybean 5 produced the highest seed yield (2373.70 kg ha-1) followed by control treatment (1887.90 kg ha-1) at the same variety. On the other hand, the plants consequential from 500 Gy ?-ray radiated of BARI soybean 5 had shown the lowest seed yield (1050.70 kg ha-1). This result indicating that irradiation significantly decreased on seed yield with increasing doses of gamma rays. So, the variety BARI soybean 5 and 200 Gy ?-ray alone or combination had outstanding superiority for plant growth over the other gamma ray levels.DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22199 J.

Abstract In hot and arid regions, drought stress is considered as one of the main reasons for yield reduction. To study the effect of drought stress, iron spray on the yield and yield components of corn, an experiment was carried out during the crop seasons of 2013 on research Farm in Faizabad of Iran, as a split plot within randomized complete block design with three replications. The main plots with irrigation factor and four levels were considered: level A) 50 ml evaporation from pan evaporation; level B) 100 ml evaporation from pan evaporation; level C) 150 ml evaporation from pan evaporation and level D) 200 ml evaporation from pan evaporation. Sub plots were considered with iron spray in three levels, included level A) 80 g/ha, level B) 130 g/ha and level C) 180 g/ha. The drought stress reduced seed yield, the 1000-kernels weight (TKW), the number of seeds per ear, the number of seeds per row in ear, the number of rows per ear about 39%, 6%, 31%, 14% and 27% less than control treatment, respectively. Using iron, as compared with control treatment, causes the increase of 1000-kernels weight from 295 to 311 g and the increase of seed yield from 5188 to 7078. The results obtained from the present research showed that iron spray has fairly improved the effects caused by drought stress.

In this work the suitability of several plant species for phytoremediation under natural and artificially installed conditions was studied. Brassica napus, Medicago sativa, Zea mays, Triticum aestivum, and Hordeum vulgare were grown in pots with sewage sludge from Sindos Main WWTP in Thessaloniki and from Sindos Industrial WWTP in Thessaloniki, Greece. The first series of experiments included comparing measurements of various parameters for the above mentioned plants and the sludge to those for control samples (the same plants growing in compost). It was shown that shoot growth was less reduced in T. aestivum and H. vulgare than in the other plant species studied. B. napus had lower germination tax, followed by M. sativa with the lowest germination tax. Generally B. napus, giving less biomass production than Z. mays and T. aestivum, is characterised by a higher ability to accumulate heavy metals like Cd, Cu, Ni, Pb, Zn, Cr, As and Hg. The second series of experiments included comparing measurements of various parameters of B. napus grown in sludge and treated each 7 days with metal solutions of Ni, Zn and Pb containing 10-2mg/l, 10-4mg/l, 10-6mg/l of each metal, to those for control plants treated with double distilled water. Results showed that shoot growth of B. napus were increased at treatments with lower concentrations of metals (10-6 mg/l) and control (treatment with d-distilled water). At the same time uptake of metal ions was increased with the concentration of the solution, i.e. at higher concentrations (10-2 mg/l). It is truly for Pb and Zn, transfer coefficient TC of which (indicates a plant’s potential to concentrate a metal) was quite high 15 % and 7 % correspondingly. It was noticed that B. napus has high ability to accumulate Cr, from the other hand it did not accumulate Ni (at present case).

An experiment was conducted at Madaripur and Gazipur during rabi (winter) season of 2012-13 and 2013-14 to determine the optimum dose of B for different varieties of chickpea (Cicer arietinum L.). There were 12 treatment combinations comprising three varieties (BARI Chola-5, BARI Chola-8 and BARI Chola-9) and four levels of boron (0, 1, 1.5 and 2 kg ha-1) along with a blanket dose of N20P20K25S10Zn2 kg ha-1. Boron was applied as H3BO3. Results showed BARI Chola-9 with 1.5 kg B ha-1 produced the highest seed yield of 1338 kg ha- 1 at Madaripur and 2218 kg ha-1 at Gazipur. Nodulation, nitrogen (N) and protein contents were also found highest for the same variety and B treatment. The other two varieties (BARI Chola-5 and BARI Chola-8) also performed higher yield in the plot receiving 1.5 kg B ha-1 compared to 1 kg B ha-1 or 2 kg B ha-1 at both locations. The results suggest that BARI Chola-9 and 1.5 kg B ha-1 along with N20P20K25S10Zn2 kg ha-1 could be used for achieving higher yield of chickpea in calcareous and terrace soils of Bangladesh.Bangladesh J.

The role of different nutrient elements is well established in plant metabolism. However, different crops respond differently in relation to their growth and yield. An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to evaluate the response of sulphur and zinc nutrition to the seed yield and oil content of mustard (cv. BARI Sarisha-14). It, laid out in RCBD with three replications was consisted of four levels of sulphur (0, 20, 40 and 60 kg ha-1) and Zn (0, 1, 2, 3 kg ha-1). It was observed that 60 kg Sulphur ha-1 gave significantly highest seed yield, oil content and harvest index owing to the highest number of branches plant-1, siliqua plant-1, seeds siliqua-1 and 1000-seed weight. Conversely, 0 kg Sulphur ha-1 provided the lowest seed yield and oil content of mustard. Again, the highest number of braches plant-1, siliqua plant-1 and seeds siliqua-1 was found at 3 kg zinc ha-1 which resulted in the highest seed yield, oil content and harvest index. The lowest performance of the yield components and yield was observed at 0 kg zinc ha-1. Interaction effect between 60 kg sulphur ha-1 and 3 kg zinc ha-1 provided the highest seed yield and stover yield because of the highest number of branches plant-1 and seeds siliqua-1 and the worst yield performance was a observed at the control treatment. Therefore, the application of sulphur and zinc at the rate of 60 kg ha-1 and 3 kg ha-1, respectively could be applied for BARI sarisha-14 for higher seed yield.

A  Field experiment was conducted during winter season at 2015 – 2016 at the experimental farm, department of Field Crop, College of Agriculture, University of Baghdad / Jadriyah to investigate effect of Organic Fertilizers preparation from weed plants on various broad bean varieties behavior and relationships with seed yield and its components. A randomized complete block design (RCBD) arranged according to split-plots used with three replicates including four organic fertilizers prepared from weeds Licorice (Glycyrrhiza glabra), Mallow (Malva rotundifolia), Purslane (Portulaca oleracea), European Heliotropic (Heliotropium europaeum), chemical fertilizer and control (without fertilizer) treatments, main plots included three varieties of Bean (Netherlands, Spanish and Locality ). The results showed that application of fertilizers significantly effect on studied characters, the treatment of Glycyrrhiza glabra gave higher rate of yield 3417 Kg ha-1, and There were no significant differences between Glycyrrhiza glabra and chemical fertilizer (NPK) at seed yield. Application of NPK showed highest No. of branches per plant, leaf area, thus reduction the flower portion percentage (4.02%) and increase pod numbers per plant and seed number per pod compared to control treatment. The results showed significant differences between varieties. The Spanish variety gave highest means of No. of branches per plant and leaf area per plant, thus reducing the flower portion and increase the number of pods per plant, number of seeds per pod and seed yield 3231 Kg ha-1. The Netherland variety gave higher weight of 100 seeds 47.94 g than the other varieties. Also, the most of characters were significantly influenced by interaction between varieties and fertilizers.

Twelve modern summer mungbean cultivars were evaluated to assess morpho-physiological characters, yield attributes and seed yield. Results revealed that high yielding cultivars, in general, showed superiority in morpho-physiological characters and seed yield/plant than the low yielding cultivars. However, in case of unit area basis, result revealed that seed yield/ha was greater in low yielding cultivars than the high yielding ones, yet they produced lower seed yield/plant compared to high yielding ones due to increase number of plants per unit area and these low yielding cultivars also matured 10 - 15 days earlier than high yielders. Among the cultivars, BINAmung-5 produced the highest seed yield/ha (1711 kg/ha) with lower HI (20.0%) and took longer days to maturity (69 days). On the other hand, BARImung-6 showed second highest seed yield (1697 kg/ha) with highest HI (32.6%) and matured earliest, took 60 days after sowing that might be fit the existing cropping pattern in Bangladesh.

Seeds of cv. Restoler and Noor of sunflower (Helianthus annuus L.) were subjected to 0.5 to 50 krad 60Co gamma radiation (1 rad = 10 mGy) and grown to maturity in a greenhouse. Two low dosages, i.e., 1 krad in cv. Restoler and 3 krad in cv. Noor, caused statistically significant stimulation of vegetative growth and seed yield (both total number and weight). For cv. Noor, 3 krad also significantly stimulated the weight of an individual seed. Significant declines in the yield of mature seeds occurred only at critical dosages of > 10 to 20 krad.

A field study was conducted at the experimental farm, College of Agriculture, Abu-Ghraib, Baghdad, Iraq during the period from mid. of March 2012 to mid. of July 2014 to investigate the effects of plant growth regulators and foliar application stages on seed yield and it’s components of two alfalfa cultivars. Layout of the experiment was R.C.B.D. arranged in split-split plot with three replications. Cultivars (local and hamedan) were assigned as a main plot and foliar application stages (vegetative growth, flower buds emergence, 50% flowering and 80% flowering) were assigned as sub-plots, while growth regulators (Alar, Ethephon, Naphthalene acetic acid (NAA) and control treatment) were assigned in the sub-sub-plots. Result showed that there were no significant differences between local cult. and c.v Hamadan in seed yield and it’s components except 1000 seed weight. Foliar application of growth regulators at flower buds emergence significantly increased No. of racemes per stem and No. of seed per pod, therefore it produced highest seed yield (450 kg/ha) as a mean of two seasons. In 1st seed crop, there were significant interaction between cultivars and foliar application stages on seed yield since local cult. gave highest seed yield (479.6 Kg/ha) when it spraying at flower buds emergence stage with an increasment 14.5% compare with hamedan C.V. foliar application alar significantly increased No. of seeds per pod and seed yield in both season , but it was not significantly different than NAA. Since, increasment in seed yield compare with ethephon and control treatment reach (25.4, 18.3), (18.8, 17.7) in 1st and 2nd seed crop respectively. as average for two seasons, higher seed yield (565 Kg/ha) can be obtained from sowing local cultivar and foliar application of alar when the stand reaches at flower buds emergence stage.

A field trails was carried out during winter season of 2017-2018 and 2018-2019 at Field Crops Department - College of Agricultural Engineering Sciences - University of Baghdad / Jadriyah to study the effect of salicylic acid spraying on yield and it's components of linseed cultivars. Randomized complete block design (RCBD) arranged within split plots was used with three replicates. The trail included three salicylic acid concentrations (100, 200 and 300 mg L-1) in addition to control treatment (distilled water spraying) within main plots and three linseed cultivars (Syrian, Egyptian and Iraqi local) within sub plots. The results showed that the Syrian cv. produced the highest number of main branches 7.09 and 7.11 branch plant-1, sub branch 28.45 and 27.10 branch plant-1 and number of capsules 122.39 and 117.89 capsule plant-1, number of seeds 8.63 and 8.45 seed capsule-1, seed yield 1.19 and 1.17 mton ha-1, while the Egyptian cv. gave highest means of 1000 seeds weight 6.83 and 6.54 g for the two seasons, respectively. The results showed that the spraying of salicylic acid at 200 mg L-1 significantly superiored and produced the highest number of main branches 7.10 and 6.82 branch plant-1, sub branch 29.05 and 26.48 branch plant-1, number of capsules 120.48 and 114.54 capsule plant-1, number of seeds 8.44 and 8.26 seed capsule-1 and seed yield 1.19 and 1.15 mton ha-1, for the two seasons, respectively. The interaction between the two factors had significant effect on all studied characters.

AbstractThe presence of biofertilizers can affect the life and movement of subterranean organisms in the soil. In the current study, the effect of three biofertilizers (Unigrow, Rhizogold and Rhizogold Plus) alone and in combination with diatomaceous earth (DE) and insecticides on mortality and movement of subterranean termites, Coptotermes heimi (Wasmann), was investigated under laboratory conditions. The mortality of termites in soil mixed with biofertilizers was low as compared to the control treatment, which led to significant mortality. Length of galleries formed by termites with the addition of Unigrow in the soil was significantly higher as compared to the other two biofertilizers and control treatments. Mortality increased in the presence of insecticides and DE in the soil substrate. Unigrow mixed soil having chlorfenapyr had maximum mortality and minimum gallery length followed by Rhizogold and Rhizogold Plus. The addition of DE and insecticide further enhances mortality, and we recommend that some toxic elements should be incorporated in biofertilizers to control subterranean termites.
